| Abstract Scope |
This study evaluates feasibility of utilizing low-cost feedstock and sustainable flux – RedMud for Electroslag additive manufacturing (ESAM) process, a high productivity technique offering deposition rates of up to ~45 kg/hr. for heavy (>1 ton) near net shape production. In this research, we demonstrate >99% pure iron nugget production using Direct Reduced Iron (DRI) and RedMud, a byproduct of alumina extraction process, as the flux using a furnace-based experiments. The results highlight the potential of RedMud as an effective flux in the ESAM process. We will further investigate the process using in-situ neutron diffraction technique to understand the kinetics of slag-iron interaction. This will assist in developing a thermo-mechanical-chemical prediction model for DRI-RedMud based ESAM using CALPHAD. This will provide information for estimating deposition rates with low-cost feedstocks - DRI and optimize flux compositions for faster, cost-effective, and sustainable manufacturing techniques. |
